Sometimes you want to inspect the `source()` of an `Error`.
|
|
|
|
|
`chainerror` implements `std::error::Error::source()`, so you can get the cause of an error.

Note, that because we changed the output of the error in `main()` from
|
|
|
|
|
`Debug` to `Display`, we don't see the error backtrace with filename and line number.

|
|
|
To enable the `Display` backtrace, you have to enable the feature `display-cause` for `chainerror`.
